Keyless BMW Cars Prove To Be Very Easy To Steal

July 7, 2012 by 84 Comments

A lot of higher end cars are now coming out with RF fobs that unlock and start the car. There is no longer a physical key that is inserted in the ignition. It turns out that for BMW this means stealing the cars is extremely easy for a sophisticated criminal. We always liked the idea of metal keys that ALSO had a chip in them. The two-tiered security system makes sense to us, and would have prevent (or at least slowed down) the recent  rash of BMW thefts that are going on in the UK.

So here’s the deal. A device like the one seen above can be attached to the On-Board Diagnostic (ODB) port of the vehicle. It can then be used to program a new keyfob. This of course is a necessary feature to replace a lost or broken device, but it seems the criminals have figured out how to do it themselves. Now the only hard part is getting inside the car without setting off the alarm. According to this article there are ultrasonic sensors inside which are designed to detect intrusion and immobilize the vehicle. But that’s somehow being circumvented.

You can check out a keyfob programming demo, as well as actual theft footage, after the break.

Minot Makers Launch Red Bull Too!

July 7, 2012 by 6 Comments

When we posted our redbull firing pneumatic cannon, we got a pretty quick email from [Ryan] at Minot Makers. Apparently, they were working on a redbull cannon as well. Theirs, however, has a completely different use. They intend for this to fire a redbull with a gentle arc allowing you to simply catch and drink it. They appear to be firing over a fairly short distance, so this isn’t any more dangerous than, say, tossing a drink to a friend a few feet away.

Their approach to handling the barrel size/can size difference was to build a piston cannon instead of a sabot. This conveniently also allows for easy firing of pretty much anything that will fit! [Ryan] described some future plans to give this an r/c platform allowing it to drive around at events and deliver beverages. That would be pretty cool.

Set Your Arduino Free With Wifino

July 6, 2012 by 7 Comments

[Tod] wrote in to tell us about his latest project. It’s called wifino, and aims to set your Arduino free by offering a web-based IDE, online storage for your Arduino sketches, and even WiFi enabled hardware to upload sketches wirelessly.

The wifino was conceived with the same train of thought as the codebender IDE we saw earlier this week. Instead of only providing a web-based programming environment, the wifino works in conjunction with wifino hardware, meaning you can upload sketches over a wireless connection.

On the software side of things, the wifino IDE features code editing, compiling, and uploading right from a browser. There are plans for a github-style interface in the works, allowing for the easy sharing of Arduino sketches from makers around the world.

[Tod] is planning on getting a Kickstarter underway in the next few weeks to get the wifino boards out into the wild. We’ll be sure to keep you updated with any info or specs that come our way.

You can check out [Tod] uploading code from the Windows and iOS clients after the break.

Data Mining And Saving Money With Octopart’s Historical Pricing

July 6, 2012 by 6 Comments

[Greg Shikhman] is at Octopart this summer as a software development intern. In between the time he’s spending getting coffee for the other devs, he came up with historical pricing for thousands of components available at Octopart

There’s a lot of cool data out there, like this bit of pricing info for a 555 timer. We’re guessing a few people were out of stock of 555s around the end of May, explaining why they were selling (well, available for) $1.68 a piece. If you’re trying to source components, it might be worth your while to check out Octopart’s historical price index. Buying a PIC microcontroller last August was a roll of the dice; in one day the price changed from $5 to just over $2.

With all this data, it’s even possible to data mine for real life events unrelated to shipping and stocking issues. Japanese manufacturer Renesas was hit pretty hard by last year’s earthquake, and this shows up in the historical prices for one of their microcontrollers. Not bad for an intern’s project.

OpenGL On The Raspi

July 6, 2012 by 8 Comments

Perhaps we’ve been concentrating too much on the hardware side of the Raspberry Pi. Sure, connecting the Raspi to the outside world through GPIO pins is cool, but let’s not forget we’re dealing with a full-fledged Linux box here. [chris] is doing his best to keep us in check with by bringing the power of OpenGL graphics to the Raspberry Pi.

Previously, OpenGL ES was only available for xorg but [chris] successfully added support for Raspbian. There’s a great physics demo [chris] put together showing off 128 spheres and cubes bouncing around a plane.

Right now, [chris] is looking for people to contribute samples and tutorials for making accelerated 3D graphics on the Raspi. You can grab all the code over at [chris]’ Git and contact him over on the Raspberry Pi forums if you’d like to help out.

As with any graphics demo, check out the videos after the break.

Fritz’s, Fast Food With A Robotic Slant

While at Maker Faire K.C. this year, I was sure to take my family to a spot we tend to visit every time we are near: Fritz’s. Fritz’s is a restaurant with an interesting food delivery method. The food itself is your standard faire of burgers and fries, however the railroad theme comes into play when your food is delivered by a model train on a track that runs along the ceiling. Your tray of burgers is deposited safely on a platform that is lowered (hydraulically?) to your table. The whole thing doesn’t look terribly complex, but it is fantastic fun.

Lift Beer With Quadcopters, Win Prizes

July 6, 2012 by 2 Comments

If you have a quadcopter and are looking for a beer delivery device, HobbyKing is putting on a beerlift competition The rules for the HobbyKing beer lift are pretty simple: lift the most beer with a quad/hex/octo copter and win a HobbyKing gift card.

There are 3 classes: Unlimited, which means a vehicle of any size goes, a 700 class for copters with a motor-to-motor diameter of 700 mm or less, and a Disaster class for the coolest crash.

So far the largest lift is a monsterous 2 meter octocopter by [Muresan Alexandru Camil] capable of lifting just over 47kg. In the 700 class, a bizarre looking 9-rotor copter built by the Whac-A-Mole flying team was able to lift 28kg.

The disaster category, a smaller quad built by [Gabriel Devault] was barely able to lift four cans of Coors Light water, while the current disaster class leader made a few valiant efforts to lift a keg. Protip: if you’re doing a blooper reel, Yakety Sax is definitely the way to go.
